Mandela, 47, began growing her hair out 25 years ago as a "spiritual calling," and since then she has amassed 39 pounds of dreadlocks which stretch an astonishing 55 feet, 7 inches -- longer than a bus. Unsurprisingly, Mandela holds the Guinness World Record for longest dreadlocks, a record she set in 2009, though her dreadlocks are even longer now.
